E.On said the supply would be enough to power every household in the country consuming an average of 2,500 kWh.

It is the first time the country’s renewable energy supply has topped 100 billion kWh in six months.

The increases reflect the expansion of wind and solar power installations under Germany’s long-term drive towards a low-carbon economy, as well as the exploitation of storms.

The highest input of renewables into the country’s energy grid came on 3 January, when Cyclone Burglind pummelled Europe. Powerful winds accounted for much of the 1.1 billion kWh energy generated, more than 71 per cent of the Germany’s electricity consumption that day.
